metallb add-on

This README provides steps to install metallb load balancer for Kubernetes cluster as Nirmata add-on.

When to use metallb?

Public cloud providers offer loadbalancer type service which makes it easy to expose an applicaation outside the cluster. Metallb provides similar service for applications running on on-prem clusters. Metallb requires a routable ip range to provide an IP address to the services exposed outside the cluster. Metallb can support either layer-2 mode or BGP mode to access the service and advertise the routes. This configuration is tested in layer-2 mode.

Validated Versions

**Metallb Version - 0.8.3 Nirmata Version - Cloud Edition Kubernetes Version - v1.16, v1.17, v1.18, v1.19
